Operating voltage
3.0 V to 3.6 V @ 16 MHz *1
*1 : Varies with conditions such as the operating frequency (see Section “s ELECTRICAL CHARACTERISTICS”) ,
Assurance for the MB90V370 is given only for operation with a tool at power supply voltage of 3.0 V to 3.6 V,
an operating temperature of 0 °C to +25 °C, and an operating frequency of 1 MHz to 16 MHz.
*2 : I2C can detect the arbitration lost when another I2C starts another communication at the same time.
*3 : After reset, PF5 to PF7 serve as general purpose I/O pins in MB90F377; however, these pins serve as V1, V2
and V3 function in other products.
